121-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 24 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Species by species, here's what the data says the year looks like.
Lastman Lake maps at 121 acres behind 3.4 miles of shoreline. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 81% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 1.4 mi, about 0.2 mi across. It sits in Cariboo Regional District. Its nearest charted neighbour, Big Onion Lake, is 6 mi to the north.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 6 to 24 ft, then a winter hold in 5 to 24 ft. Start at Break off the point. It's a drop-off holding about 11 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 6 to 24 ft | dawn & dusk | Break off the point (11 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 7 to 24 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 5 to 24 ft | dawn | Break off the point (11 ft) | Jigging spoon, Tube jig (white) |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 20 ft.
